I prefer pikvm instead. They support cheap HDMI to CSI boards that have lower latency. And they don't make you pay for some features like tiny pilot does. This site sounds like a hobby one but it's actually a commercial product.

I still don't think I'll use it though. I can understand you're trying to make a business out of it. But the password protection feature is one that's too big to do without even in my home network.
For the other stuff like remote mounting drives I can imagine you're asking money for. But the password is pretty essential IMO, as is HTTPs. And the license drives the price far above $100.
Nevertheless I wish you luck with your business!
Fwiw I think pikvm is going the same route now, selling premade hardware. It's nice but the price is just too high for hobbyists. Some of my servers didn't even cost me $200 new and that's with iLO included.
Heck it could even be powered by the USB host. It would be an "active cable" that doesn't require any custom software. Would be super convenient to carry with a laptop for data center technicians.
